Title: Liquid crystal display device
Inventor: HASHIMOTO YOSHITO
IPC: G02B5/00
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of emitting light beams having high parallelism toward liquid crystal display elements. SOLUTION: A sheet with light shielding slits 20 is provided between liquid crystal display elements and an irradiating part. Many light shielding materials 26 are arranged parallel with each other on the surface of one side of a sheet 25 having translucency and parts of the sheet 25 in which the light shielding materials 26 are not provided become slits 27 to make light beams from the irradiating part pass. The sheet with light shielding slits 20 makes light beams made incident on the light incident plane at right angles or almost at right angles pass as they are from the slits 27 and, on the other hand, interrupts light beams made incident on the light incident plane obliquely or exteremely obliquely by the light shielding materials 26.  Consequently, since light beams having high parallelism are obtained in a direction perpendicular to the surface of the sheet with light shielding slits 20, the light beams having high parallelism are emitted toward the liquid crystal display elements.

Title: Hand-written image display device
Inventor: KITAGUCHI TERUYUKI
IPC: G06F3/0488
Filed: 1993-03-08
Abstract: PURPOSE:To improve the visual recognition of both of initial image data and hand-written data by reducing the density of already inputted image data and displaying the density-reduced image data at the time of inputting a hand-written image in a hand-written image displaying device for inputting and displaying hand-written data in addition to the original image data. CONSTITUTION:A handwriting mode indicating part 102 specifies a handwriting mode judging flag. In the case of a handwriting mode, a density determining part 103 determines the display density of image data so as to change it to a low level. An image display control part 105 controls a display part 108 so as to display image data read out of an image data storing part 104 by the density determined by the determining part 103. On the other hand, a handwriting display control part 107 controls the display part 108 so as to display handwriting data inputted from a handwriting input part 106 by density relatively higher than that of the image data. Then the display part 108 displays both data on the same display screen. Consequently handwriting data can easily be inputted at the time of adding, correcting or editing data.

Inventor: YAMADA TAKAHIRO
IPC: H01Q3/01
Filed: 1990-02-27
Abstract: PURPOSE:To improve the arrangement density of antenna segments by setting rotary angles which leave center axes actually orthogonal to a radio wave confronting surface to a value in which phases in the common connection conductor of a connection means for respective radio wave signals are the same. CONSTITUTION:Helical antenna elements 511-5mn are provided for respective segment substrates 31-3m and the rotary angles beta at the tips of respective helical antenna elements are decided so that a radio wave signal phase difference between the elements comes to the integer-fold of one period of a zero radio wave signal. At that time, there is no phase difference between the radio wave signals of respective elements in the common connection conductor 8. Thus, it is unnecessary to set a distance between segment substrates 31-3m in the arriving direction of a radio wave to be D=a.lambda(alpha=integer and lambda=space wavelength), and the segment substrates 31-3m can be arranged in a minimum pitch pg, whereby the segment substrates 31-3m can be arranged in highest density.

Title: Color image recording method
Inventor: OKINO YOSHIHARU
IPC: B41J2/44
Filed: 1987-03-03
Abstract: PURPOSE:To easily record a color image by condensing the light beams of 3 kinds of wavelengths emitted by semiconductor lasers to one beam and scanning and exposing a photosensitive material by said beam. CONSTITUTION:The light of 656nm wavelength from the 1st semiconductor laser 251, the light of 750nm wavelength from the 2nd semiconductor laser 252 and the light of 830nm wavelength from the 3rd semiconductor laser 253 arrive at a mirror 263 by passing the same optical path. These light beams are directed by the mirror 263 to a polygonal mirror 270 through the same optical path 264 and are reflected by said mirror; further, the beams are reflected by the rotation of the mirror to scan and expose the photosensitive material S via an ftheta lens 280 and a cylindrical mirror 290. The photosensitive material S is a pressure-sensitive color photosensitive material having effective sensitivity respectively at the light beams near 656nm, 750nm and 830nm wavelengths. Said material moves in the direction orthogonal with the scanning direction of the laser light. The color image is thereby easily recorded without requiring a costly and large-sized device.

Abstract: PURPOSE:To enable intermediate gradations and color images to be favorably reproduced while effectively preventing irregularities from being generated in image density, by a method wherein nonuniformity in heat accumulation due to differences in current-passing timing is corrected by calculations performed in consideration of variations in thermal energy. CONSTITUTION:A buffer memory 51 supplies an Xi calculator 55 with the present and past image information with a picture element under consideration as a reference, and the amount Xi of heat accumulated at the picture element under consideration is calculated. A counter 56 outputs a unit heating element kind discrimination signal for discriminating the relationship between the picture element under consideration and four kinds of unit heating elements (a)-(d), and is provided in correspondence with the fact that the heat accumulation condition differs for different ones of the unit heating elements (a)-(d). Data obtained by the Xi calculator 55 are supplied to a Ti calculator 58, which is supplied also with future picture information discriminating image data from the buffer memory 51. By using the data 54 and 59, the calculator 58 calculates a width of a pulse to be impressed on the picture element under consideration, and supplies it to a driving-controlling circuit 61.

Filed: 1990-02-27
Abstract: PURPOSE:To obtain a charging system in which an AC power source is unnecessary by charging a secondary battery with a current from a telephone line by means of an automatic operation or a manual operation when the secondary battery shows a charging requiring voltage. CONSTITUTION:When a display circuit 3 displays the charging requiring voltage of the secondary battery 1 and urges a user to charge, the user uses a dial circuit 7, and closes the telephone line 9.

When the secondary battery 1 is charged to a certain degree, the line close holding circuit 8 is restored by the output of a timer 5a. Thus, the charging system in which the AC power source is unnecessary can be obtained.

IPC: F16H27/04
Filed: 1988-02-29
Abstract: PURPOSE:To make visual recognition of the travel process of a reciprocating cylinder within a single and the same display range possible by continuously transmitting the torque of a rotary body of the driving side to the rotary body of the driven side while making the rotary body of the driven side to intermittently rotate at the time of reverse rotation. CONSTITUTION:When a rotary body 22 of the driving side rotates in a linked motion with a drive shaft of a hydraulic pump or the like, a timing lever 31 is not obstructed by a guide body 34 and maintains the condition of contact with engagement pins 30a, 30c. As a result, the torque of the rotary body 22 of the driving side is continuously transmitted to a rotary body 25 of the driven side. When the rotation is reversed, a guide body 34 comes in contact with the tip of a timing lever 31 so that it is guided to separate from engagement pins 30a-30c along the guide body 34. As a result, the continuous rotation of the driving side rotary body 22 is intermittently transmitted to the driven side rotary body. As a result, the amount of the advance of a display hand 23 changes depending on the directions of the rotation.
